Problems with warp marker creation based on hitpoints on Kick

Hi at all,

I have a multitrack drum recording in Cubase and want to detect hitpoints only from the Kick In mic. All tracks are in a folder and group-based / phase-based editing is enabled.

I open the tracks with double click, and set the hitpoint detection. Alle looks nice, the hitpoints are shown correctly (see screenshot)

When i now create warp markers out of the hitpoints the markers are created on all tracks. But very often not on the detected hitpoints. What I´m doing wrong?

Bug or my error?
